Answer:
Plant A produced 15,000 panels.
Step-by-step explanation:
Let plant B produce x panels
Plant A then produced x - 2000 panels
2% of panels from plant A were defective
3% of panels from plant B were defective
The two plants together produced 810 defective panels so;
2/100(x - 2000) + 3/100(x) = 810
0.02x - 40 + 0.03x = 810
0.05x = 850
x = 17,000 panels
So plant B produced 17,000 panels
Plant A produced 17,000 - 2,000 panels = 15,000 panels.
Answer:
Step-by-step explanation:
13. 2,300mg > 2g
14. 3kg = 3,000g
16. 4120mg = 4.12g
17. 75g < 800mg
16/20. We reduce that and get 4/5.
After this it's much simpler to chage it.
100 dividied by 5 is 20. (20,40,60,80,100)
So the 4th number (4/100)
is 80. 80%.
20% she didn't and 80% she did :) (100-80)
It’s either volume or matter
